Wiikey Fusion Wont Play Wii Games

I had originally Soft-Moded my Wii but I wanted to play other countries games on disc so I bought the Wiikey Fusion. I downgraded from 4.3 to 4.1 then I installed my Wiikey fusion. It has 1.5 and it can play Gamecube backups from disc but whenever I try to play a Wii backup NTSC or Pal or Jap-NTSC it just boots back to the Wii Home menu. But I can boot all of my NTSC games normally when the Wiikey Fusion is off. The Wiikey fusions boots my original wii games though.
